Installed one in June and it died in September along with accompanying SS reg/rec. Looking for something from the list compiled by Mriggs. I read on another site that a person there had ordered an electrosport stator #esg 730. Dimensions were the same id and od was 104mm(xscharge is 103mm), thickness is 15mm as opposed to the 20m of the xscharge part. That may not be a problem. I haven't removed mine yet to check clearance of the rotor inside diameter. The esg740 was same as 730 except 22mm thick, numbers provided to me by the sales manager at Electrosport . A note: pictures of electrosport parts often shown on sales websites are of older better insulated parts. I asked about this specifically during an online chat with a person at powersports in Austin. He said the one they sell is the one pictured on their website. That is not the part you will see,sometimes, if you just type in the es part # on a search page. Some pictures show a very well insulated stator. Most of the new stators offered look a lot like the xscharge, but not identical, mostly in the cheapness category.
